Computational Mechanics Research Laboratory


Welcome to the research group website of Dr. Jorge Belinha at the Faculty of Engineering of the University of Porto (Portugal) and INEGI-UP (Unit of Conception and Experimental Validation):

the Computational Mechanics Research Laboratory (CMech-Lab).

The goal of CMech-Lab is to develop and extend advanced discretization numerical techniques to new demanding fields of computational mechanics, enabling the investigation of emerging theories and numerical techniques in applied mechanics. The work developed in CMech-Lab is highly interdisciplinary, combining civil, mechanical and biomechanical engineering, applied mathematics, computer science, and materials science. The researchers of CMech-Lab come from distinct backgrounds: Civil Engineering, Mechanical Engineering, Biomechanical Engineering, Biology, Mathematics, Dental Medicine or Medicine. All the research developed in our research group come from original software developed at CMech-Lab, using several programing languages, such as FORTRAN, C++ and Matlab.

Research topics

Our research focus mainly in the following computational mechanics topics:

- Material non-linearity (elastoplasticy, hyperelasticy)

- Nonlinear large deformations

- Fracture and Damage mechanics

- Contact problems

- Topologic optimization

- Heat transfer

- Thermal Structural Analysis

- Buckling and Dynamic analysis

- Bone tissue nonlinear behaviour

- Bone tissue remodelling (Mechanological and Mechanobiological)

- Fluid flow analysis (low velocities)

Research Methodology

Here, at CMech-Lab, the previously mentioned computational mechanics topics are solved using several numerical techniques, such as:

- Finite Element Method (FEM)

- Element Free Galerkin Method

- Point Interpolation Methods (PIM, RPIM and NNRPIM)

- Natural Radial Element Method (NREM)

FEMAS - Finite Element and Meshless Analysis Software

FEMAS is a Finite Element and Meshless Analysis Software fully developed by Dr.Jorge Belinha. FEMAS possesses a graphical user interface (GUI) running in Matlab environment.

It permits to study structural problems considering 2D/3D approaches, assuming one of the following analysis:

- Linear Elasto-static analysis

- Free Vibration linear elastic analysis

- Buckling linear elastic analysis

- Elasto-plastic non-linear analysis

- Bone tissue remodelling analysis

- Fluid flow analysis (low velocities)

- Thermo-mechanical analysis

- Fracture mechanics

FEMAS uses the following discretization methods:

- Finite element method (2D triangular elements with 3, 4 and 6 nodes and 2D quadrangular elements with 4, 8 and 9 nodes, and 3D tetrahedral elements with 4, 8 and 10 nodes and 3D hexahedral elements with 9, 20 and 27 nodes)

- Meshless methods using radial point intepolation technique (2D and 3D)

FEMAS is structural analysis software, design for students and academics. It is a free software and it should not be used for commercial purposes. FEMAS is still under development and every year (day) more features are included.
